``The Judicial Panel on Multidistrict Litigation is weighing a motion to consolidate 23 suits from around the country that claim Fannie and Freddie owe real estate transfer taxes on foreclosed homes they resold. The total exposure for Fannie and Freddie, which are now in federal conservatorship, hasn't been publicly tabulated, but in the two cases that sparked the MDL motion, the Michigan attorney general and the county government of Oakland, Michigan, claimed that Fannie and Freddie owe millions in transfer taxes just to Oakland County. Class actions already on the dockets have asserted claims on behalf of 13 states, but according to a consolidation motion filed by Genesee County, Michigan, 35 states have real estate transfer tax statutes that could be asserted against Fannie and Freddie.''
